(KNZA)--A public health advisory has been lifted for the Atchison State Fishing Lake in Atchison County.

That word came in a joint release Friday from the Kansas Department of Health and Environment and the Kansas Department of Wildlife and Parks.

The advisory had been issued last month due to the presence of blue-green algae.

The release says advisories are lifted when cell densities and toxin concentrations dissipate to levels below the Watch thresholds.

Six lakes in the state remain under health advisories due to blue-green algae.
